Anti-Müllerian hormone (AMH) is a dimeric glycoprotein that is produced by granulosa cells in females and it is currently considered to be the most reliable biomarker for the assessment of ovarian reserve in women. The AMH secretion in ovarian granulosa cells starts at approximately the 37th week of pregnancy and it reaches peak values in the bloodstream around the age of 25 years. After this, it gradually declines until menopause, when it becomes undetectable.
